How long has he not been eating? Was he eating well prior to that? Have you had him checked at the vet yet?

He is only eating a little food in the evenings (Wellness Complete). He was eating very well before flying here. He was seen by his vet for his yearly in Dec and a gain last week for his health certificate and had gained 5lbs. I was waiting until the 1st of next week (Monday) and if he's not eating better I was taking him to a local vet.
